How to plow the field? (Medieval Dynasty)

We appoint people to the barn by field workers. We place a few small beds and in the management menu we point out all possible cultures on different beds.
Beds of 6-8 cells no longer need to be otherwise they may not have time to start sowing, having spent the whole season on digging and fertilisering a huge bed.
Immediately beds on all plants. Workers will figure out what season to sow.
And the most important thing is not to participate in the excavation or the harvest. Any of our impact cancels the task set through management.
